Expand description

A calendar implementation

Only implementors of Calendar should care about these methods, in general users of these calendars should use the methods on Date instead.

Individual Calendar implementations may have inherent utility methods allowing for direct construction, etc.

Associated Types

The internal type used to represent dates

Required methods

Construct the date from an ISO date

Obtain an ISO date from this date

Count the number of months in a given year, specified by providing a date from that year

Count the number of days in a given year, specified by providing a date from that year

Count the number of days in a given month, specified by providing a date from that year/month

Add offset to date

Calculate date2 - date as a duration

Obtain a name for the calendar for debug printing

The calendar-specific year represented by date

The calendar-specific month represented by date

The calendar-specific day-of-month represented by date

Information of the day of the year

Provided methods

Calculate the day of the week and return it
